94.5% of websites use third-party scripts like ad scripts and analytics tools. These run in the user’s browser, often beyond your team’s visibility. That lack of control opens the door to attackers, who exploit these blind spots to inject malicious code and steal data—without triggering standard security alerts.

A malicious script injection led to the leak of tens of thousands of credit card and customer records.
Multiple cosmetics brand sites
Over 100,000 credit card records were compromised through attacks exploiting vulnerabilities in external scripts.
Major global airlines and entertainment companies
Scripts modified through tag managers or chatbots were used to exfiltrate user data — leading to large-scale data breaches and substantial fines.
These incidents often stem from systemic issues, including under-resourced security teams, disconnected workflows between marketing and security, and limited visibility into platforms like Google Tag Manager (GTM).
